I am trying to run your code, but getting many errors. For example the line <br /><br />from sage.geometry.polyhedron.constructor import Polyhedron<br /><br />gives an error because there is no file named constructor in the folder geometry.polyhedron. it only contains one file named as base.py<br /><br />Any comments about this error?<br /><br />Regards<br />AssadAsadhttps://www.blogger.com/profile/09477917468271999819noreply@blogger.comtag:blogger.com,1999:blog-7797369115651164376.post-80944255306988219292013-01-21T11:42:15.761+01:002013-01-21T11:42:15.761+01:00Hey!

Then it will be reviewed and integrated into Sage as a whole.
